Always on the bleeding edge I like to use beta versions of upcoming Ubuntu releases. This sometimes poses a little problem: More often than not, there come outdated language definitions with Firefox, causing some minor annoyances.
The biggest annoyance of which is that you just can’t seem to delete those offending addons:
The solution, albeit simple, is harder to find:
Just open a terminal window and switch to superuser mode using
sudo -i
, then start Firefox from the command line using
firefox
. One Firefox is running, just open the Addon window, et voila:
Now you can remove any addon you like, even those that were locked before.
